| May 15, 2021 | education
Ev = 15 V / m.
εph = 4.7.
Eph -?
The electric field strength in porcelain Eph is determined by the formula: Eph = Ev / εph, where εph is the dielectric constant of porcelain, E is the electric field strength in vacuum.
Eph = 15 V / m / 4.7 = 3.2 V / m.
Answer: the electric field strength in porcelain is Eph = 3.2 V / m.
